Morse Code Intercom

Morse Code Intercom lets you communicate in Morse code with other users on your WiFi network or The Internet, or use its training mode to learn Morse or improve your Morse skills.

Morse Intercom starts in Intercom Mode but can be switched into its alternate Training Mode with a couple of button taps.

For most people (including me), copying Morse at a reaonable speed requires your undivided attention. So my app does not send you distracting adverts.

INTERCOM MODE:

Your Android device behaves like a traditional Morse transceiver. Anything you transmit on a particular channel will be heard by all users listening on that channel, and you will hear messages sent by any users transmitting on that channel. This version provides 20 channels.

Unlike a regular transceiver, you can restrict who hears your transmissions to a single user, or to a small net of users. See in-app help for details.

TRAINING MODE:

In training mode you can add Farnsworth delays between received characters, and you can reduce unpleasant audio clipping that would otherwise occur with certain speed/sidetone-frequency combinations by adding a slow decay to zero volume to the end of received dots and dashes. Training options currently available:

i) Local:
Your device sends you 5 character random groups. You are able to define which characters can be generated (including ITU recognised punctuation characters), and the relative frequency with which these characters will be generated. By default, only alphabetics and numerals are generated, and alphabetics are generated 5 times as often as numerals, but you have total contol over which characters can be generated and with what frequency they will be generated.

Local mode can be configured to learn using the popular Koch method. Simply define an initial two characters, store them, learn to recognise these two characters 80 to 90 percent of the time, then add another character and repeat until you've learnt the entire code.

ii) Newsfeed:
Headlines are sent to you from a BBC newsfeed in Morse code. Learn Morse and stay updated with the latest news at the same time! Tap 'Show Story' and the entire story behind the headline will be displayed in your browser.

iii) Remote
Receive training messages from other users using the app in Intercom Mode. You will probably want to restrict who can send you messages (see in-app help for how to do this).

WiFi vs Internet Startup:
When you start the app you will be asked to 'Set Startup Mode For Morse Intercom'. Start in Internet mode if you intend to use Intercom mode and you want external servers to link you to other Intercom users anywhere on The Internet NOT connected to your WiFi network. If all users you want to communicate with are connected to your WiFi network you don't need the assistance of these servers, and should probably start in WiFi mode. WiFi mode is great for family or radio club Intercom use.

If you intend to use Training mode, almost always you should start in WiFi mode. Even newsfeed reception works in WiFi mode. The one exception is if you want to receive training messages from an Intercom user NOT connected to your WiFi network.

A web version of the app can be found at http://program2anything.com/morseintercom.html (your browser must support Flash). On this page there is a link to download a desktop installable version (Windows/Mac). Android/web/desktop versions can all work togrther. NB: Currently there is no iOS version of this app.

If you like Morse Code Intercom please rate it in the PlayStore.

If you don't like Morse Code Intercom please tell me why by emailing graham.jolley.apps@gmail.com .

Morse Code Intercom is free, doesn't send you adverts, only asks for permissions it really needs and doesn't collect information about you.
